7 Application filed December T 0 all whom it may concern.

Be it known that I, SHIRLEY Soon, a citi- Zen'of the United States, residingat Wa-- kenda, in'the county of Carroll and State of Missourhhave invented certain new and useful Improvements in Anchor Ripraps, of which the following is a specification.

This invention relates to an improvement in rip raps and has more particular reference to a means adapted to be positioned at the banks of rivers or streams and wherein sand and silt will be collected in a more expeditious manner than is now possible with other rip raps used for this purpose, the primary object ofvthe invention residing in the provision of such a device or article that may be manufactured and set up at a cost considerably less than is now possible;

With the above and other objects in view as the nature of the invention will be better understood, the same comprises the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing wherein like reference characters indicate corresponding parts 7 throughout the different views,

Figure 1 is a side elevational view of an anchor rip rap constructed in accordance with the present invention, r

Figures 2 and 3 are detail transverse sectional views taken substantially upon the lines 22 and 33 respectively of Figure 1,

'- and 7 Figure 4 is an end elevational view of the rip rap shown in the other figures. 7

Now having particular reference'to the drawing, my novel rip rap comprises preferably four equally spaced substantially triangular shaped members designated respectively, 5, 6,7 and 8, which triangular shaped members are rigidly. joined together in a manner hereinafter to be more fully described. p 1 e e The construction of each of these substantially triangular shaped members is relatively the same and a description of one will su'fiice for all. As clearly shown in the oletailed views, Figures 2, 3 and 1, each of said substantially triangular shaped members comprise a pair of cross bars 9 that are formed at their opposite ends with openings for allowing a length of steel wire 10 to be guided therethrough; Suitably connected at v gitudinal wire through the openings at opposite ends of the .cross members 9'9 areother wires 14. Certain. ends of the wires 13 and 14 are *positeends thereof 3,1923. Serial No. 678,252.

their opposite ends to the vertical and transverse portions of said strip of wire 10 are cross wires 11 which forms a wire mesh screen, it being noted that the screens of the substantially rectangular shaped members 6 and 7 are of relatively wide mesh for allowing the sand and slit to pass therethrough while the screens of the end rectangular members 5 and 8 are of very fine mesh for preventing the passage of the sand or silt outwardly through the ends of the rip rap.

Interconnecting the. members 5 to 8 inclusive, is a pair of longitudinal boards 12 it being noted from a consideration of Figures 2, S and t,that these boards are secured to the cross bars 99 of each of the frame members at opposite sides of their point of crossing and are secured thereto in any manner desirable, such as by nails, staples or the li re. 1 Threaded through openings at the central point of each of the 13 while also threaded connected'to the end member 8 while the op extend beyond the opposite end member 5 and are plattedtogether at 15 for providing a cable whereby the rip rap thus formed may be anchored to the bottom of the river or stream.

It will thus be seen that I have provided a highly novel and .useful form of rip rap and one wherein the sand and silt will be more expeditiously formed atthe shore of the body of water for thereby preventing the shore from becoming cracked or washed away by the action of the water thereon.

Although I have herein set forth the most members 5 to 8 is a 'lonpractical embodiment of this invention with which I am at this time familiar, it is nevertheless to be understood that minor changes may bemade in the invention without departing from the spirit and scope ,of the apwhat Let- I combination, a plurality of pairs of bars, the

bars of each pair being arranged in cruciform relation and secured to'each other at points of intersection, spacing boards sebars and having end portions extending cured at intervals to the bars of each pair beyond oneof the terminal pairs of bars and and disposed one at each side of the points both together to form an anchor line for the 10 of the connection between the bars, screens structure.

disposed on the pairs of bars, and cables In testimony WhereofI afl ix my signature. trained through the end portions of the bars and bridging the spaces between the pairs of SHIRLEY SCOTL.
